Abstract
A blowing-type heat dissipating fan able to increase air input and pressure of output air is composed of a fixing casing, at least one cover plate, and primary fan wheel with integrated electric motor, hub and several blades. It features that said cover plate arranged at one side of said fixing casing has an air inlet, in which at least one secondary fan wheel with hub and several blades is installed.
Description
Technical field
The invention belongs to sink, particularly a kind of blower radiating fan with adding air inflow.
Background technique
As shown in Figure 1, the blast-type cooling fan of commonly using comprises shell block 1f, cover plate 2f and main impeller 3f.
Cover plate 2f suitably is incorporated on the shell block 1f, and is provided with wind inlet 21f.
During running, the air blast flabellum 33f of main impeller 3f rotates, and then sucks axial flow by the wind inlet 21f of cover plate 2f.Then, air blast flabellum 33f then the driving axial air-flow so, can dispel the heat via the side air-out mouth 12f of shell block 1f output in order to the outer desire heat radiation object of offside exhaust outlet 12f.Even so, but, therefore, can't significantly promote air inflow, so that air output and blast thereof show slightly low because the blast-type cooling fan only separately sucks air-flow outside the wind inlet 21f by the rotation of air blast flabellum 33f.
The blast-type cooling fan that another is commonly used, it is sheathed water conservancy diversion impeller with several pieces water conservancy diversion flabellums on the wheel hub of main impeller further, and the water conservancy diversion flabellum is close to the ring flat-plate of main impeller, and between the wheel hub and air blast flabellum of main impeller.In the running, water conservancy diversion impeller and main impeller rotate synchronously, increase axial admission efficient by the water conservancy diversion flabellum, with the blast of increase holding space, and the air output of lifting side air-out mouth.In fact and can't be effectively suck the extra axial flow of capacity by the wind inlet of cover plate even so, but because the water conservancy diversion flabellum almost completely amplexiforms on ring flat-plate and away from wind inlet, therefore, the water conservancy diversion flabellum.Moreover the water conservancy diversion flabellum of water conservancy diversion impeller is close to ring flat-plate, and its axial flow that also causes sucking is failed in time to turn to and directly impacted and cause the air-flow bounce-back on ring flat-plate, thereby is easy to generate flow-disturbing and noise.In addition, being provided with of water conservancy diversion flabellum is close to the air blast flabellum, so that excessive stop portions air blast flabellum, thereby causes the air blast efficient of air blast flabellum to be not so good as expection.
